To 'all'whom it may concern: f

Beit known that we, KNUTE LEIDAL and MARTIN ULRING, citizens of the -United States, residing at Webster, inthe county of Rice and State of Minnesota, have .invented certain new and useful Improvements in Carriers; and we dohereby declare the following to be afull, clear, and exact descripo the invention, such as will enable others skilled in the art to which it appertains. to

make and use the same.

. which may be supported in brackets v5 in which track wheels 6 that n brackets 5 and wheels Referring to the drawings; Figure 1 is a view in side carrier mounted on a' su porting wire or cable, with some a view in end e vation of the parts shown in Fig. 1, but with some parts shown in dotted positions, and other 1s a detail view, principallyln vertical section, taken on the line m3 ma of Fig. 2 g and Fig. 4xis a detail view on an enlarged scale, taken on the lineaA` m4 of Fig. 1.

The numeral l indicates a heavy lwireor cable which constitutes the carrier track, and the customary or in any suitable way, not shown.

he carrier frame is approximately U- shaped. in form, comprising a horizontal bar 2, and a pair `of de endin 3a having screw-'t eadeengagement with the ends of said bar 2; The bar 2 and legs 3 and 3a are also connected together 'by braces 4. To the upper side of the bar 2is secured a pair of upwardly extending angular wheel are journaled grooved runupon the overhead The brackets 5 are pivotthe upper side of said bar 2 bolts 7, which permit said 6 to oscillate slightly,

tubular legs 3 and aroun curved portions ofthe track.

. The bucket or carrier receptacle 8 is pivotally supported by the depending eg's 3 and 3a ofthe carrier frame, and to this end, the bucket 8 is, as shown, provided with a reinforcing strap 9. The intermediate portion of said strap 9 underlies the bottom of the bucket 8, the ends of which are turned up Patented Dec. 1o,1 9o7.f

as re uired when the device is runningy tubular' at right angles and secured to'the`sides of said bucket 8. Secured near the ends of said the flattened lower ends of said tubular legs 3 and 3at of the carrier frame. The trunnions 10 are located below the center of gravity of the 4bucket 3 so that the latter, when not locked to the carrier frame, will turn upside dotted lines in Fig. 2. Mounted to work telescopically within the said tubular leg 3 is a trip rod 1]. A.-coiled spring 12, compressed between the lower end'of said trip normallypresses said trip rod 11 upward. The lowerv end of said trip rod 11 is provided near its bottom end with a transversely projecting pin 1 3,`the ends of said pin worki through a pair of alined slots 14 cut in the tubular leg 3. Secured to the side ofthe bucket 8,l adjacent to the tubular leg 3, is a cam acting lock bar l15 provided at its intermediate portion with anotch 16 for enga epin 1'3, to lockthe bucket in'its operative position. vThe upper projecting end of the trip stitutes -an anti-friction head' for engagement with a tripping abutment, which is suy .ported from the track 1.

- The tripping abutment may be of any suitablev construction. The construction shown is in the `form of a cam arm 18 that is oted to the side of a block 19 secured to the track 1. The pin 13 working in the slots 14, not only limits the upward movement of the trip rod 11, but prevents the trip rod 11i-rom turning, so that the roller 17 will always be in position to be engaged bythe cam arm 18. When the litter carrier is travelinor toward the right, with reference to Fig. 1, t e roller 17 of the trip rod 11 will strike the cam arm 18 ofthe tripping abutment. the stop pin 20 on the block 19, the cam arm 18 will force the trip rod 11 down against the tension of the spring 12', thereby releasing the pin 13 from the notch l16, at which time the strap 9 are trunnions 10 that are journaled in down into a dumping position, asshown by,

' r'od 11 and thelbottom of the tubular leg '31,;`

ment with the inwardly projecting end of t e On account ,off

rod 11 is provided with a roller 17 which conpiv- I bucket 8 will be unlocked from the carrier -frame, and the bucket will automatically further from the pivot .point of the bucket 8 than the notch 16, the said cam bar 15 will cam thetrip rod 11 into its lowermost position against the tension of the spring 12, to

permit the pin 13 to enter the notch 16. As

is evident, when the carrier frame is moving toward the left, with respect 'to Fig. 1, the cam arm 18 willvswin out ofthe way to permit the roller 1 7. of t e trip rod 11 to pass,

without unlocking the vbucket 8 from the cam frame.

1. The combination with an ovel head track, of a carrier frame having whee s arranged to travel on said track, a bucketpivotally mounted on said frame, annpwardly spring-pressed vertically movable trip rod mounted on said frame for locking said bucket to saidjrame in its operative position, and a tripping abutment on .said track directly engageable with the head of said trip rod, substantially 'as described.

2. The combination with an' overhead track, of a carrier frame having 'wheels arranged to travel on said track and provided with a vertically extended tubular leg, an upwardly spring pressed trip rod mounted to beguided by and to Work telscopically within .said tubular leg for locking said bucket to in form, Wheels secured to sai-d horizontal bar and arranged to travelon said track, a bucket l pivotally mounted on the lower'ends of said depending legs, a notched latch bar carried by said bucket, a trip rod mounted to be guided by and to work telescopically within said tubular leg, a spring mounted in the lower end of said leg and compressedbetween said lower end and the lower end ofsaid trip rod, a lateral projection on said trip rod workin througlfa slot 4formed in said tubular legl or engagement with said notched bar vto lock said bucket in its operative position,

and a tripping abutment on said track directly engageable with the head of said trip rod, substantially as described.` v
